However, modifications in Hummer’s method could allow AgGO to be synthesized, free from any additional surfactants. This single-step facile synthesis provides bandgap control by varying the time of oxidation. As per our knowledge, the AgGO composite has not yet been prepared by extending the ...
Graphene oxide–silver (Ag–GO) nanocomposite has emerged as a vital antibacterial agent very recently. In this work, we report a facile one step route of Ag–GO nanocomposite formation excluding the aid of surfactants and reductants and was successfully applied to negative Escherichia Coli (E ...
Surfactants, such as cetyltrimethylammonium bromide (CTAB) are known to adsorb onto interfaces due to their amphipathic nature,11,12 resulting in reduction of interfacial free energy. CTAB has played a pivotal role in the synthesis of anisotropic gold nanoparticles. CTAB and other surfactants self-...

Another reverse electrodewetting (step 3, red arrow) cleans up the normal-concentration R18 (orange) deposited by the previous electrodewetting, making the surface inside the droplet largely surfactant-free (blue). The fluorescence intensity on a fresh silicon substrate (that is, no surfactant) ...
For example, those of skill in the art will recognize that the protein component may be obtained by isolating suitable proteins from an alternative protein source, by synthesis of proteins, or by other suitable methods. The foregoing description is not intended to limit the term “low molecular ...
(10) describe the thermodynamic parameters viz. adsorption enthalpy (ΔHo), free energy (ΔGo), and entropy (ΔSo)); ΔSoand ΔHowere estimated from intercept of Eq. (10), which equals ΔSo/R, and slope, which equals -ΔHo/R of Ln Kcvs. 1/T. The universal gas constant (R) is...
With the use of stable isotope-labeled intravenous pre- cursors for surfactant phosphatidylcholine (PC) synthe- sis, it has been shown that the de novo synthesis rates in preterm infants with respiratory distress syndrome (RDS) are very low as are turnover rates. This is consis- ...
Herein, we report the fabrication and inclusive characterization of surfactant free ZnS, CdS and CuS NPs synthesized via a simple co-precipitation technique. The prepared materials show a spherical morphology with an average diameter in the range of 5–10 nm, formed through the assembly of many ...
(N/m) is the free energy of the liquid surface; γS (N/m) is the free energy γdL (N/m) is the liquid dispersion force; p γs of the core surface; γsd (N/m) (N/m) is the core polar force; is the core dispersion force; and p γL (N/m) is the liquid polar force....
